My son, your sins are forgiven. Just say 43 Hail Mocchas, drink two stiff cappaccinos, and repent of this evil thing you have done.
Actually, it isn't a bad way to go, if the grind is consistent, and your source produces good beans. I mean, a good grinder runs $300, which is equivalent to like 50 pounds of coffee from your local shop. If you're ok with what you have, then be happy. I know that my Mazzer does a peachy job on the home-roasted beans, but the path I've chosen certainly isn't for everyone.
